Application filed November 30, 1912.

T 0 all whom it may concern:

Be it known that 1, WILLIAM CRAINE, a. citizen of the United States, residing at Brookfield, in the county of Madison and State of New York, have invented a new and useful Silo, of which the following is a specification.

This invention relates to the construction of silos, to the arrangement and method of securing doors therein. 7

An object is to provide a construction which will allow the door to be swung inwardly, the adjacent edges of the doors forming liquid tight joints, and to provide means whereby the doors may be wedged within the door frames and held securely therein.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illustrated, in which Figure 1 is a fragmental View in elevation of my improved silo. Fig. 2 is a cross sectional view taken on the line A-A of Fig.

1. Fig. 3 is a plan sectional view taken on the line BB of Fig. 1. Fig. 4: is a detail view of the means employed for preventing water from entering between the silo hooping and the door frame. This member is further adapted to retain the hooping in position and to strengthen the construction throughout.

Referring to the drawings in which similar reference numerals designate correspending parts throughout the several views,

1 is the wooden hooping of which the silo is constructed.

2 are the inside staves and represents the usual practice in the construction of the walls of the silo. Suitable openings are out within the wall, the upper and lower longitudinal edge of which is beveled as at 3 and of Fig. 2. The vertical edges of these openings are formed with the wedge-shaped edge 5 and the channel-shaped edge 6,.this construction being for the purpose that the Patented Feb. 15, 1916.

doors may suitably engage the edges in order that when in'position' therebetween, a liquid tight joint will be formed and may be maintained. Located adjacent the vertical edges of this door opening are positioned the upright posts 7 and 8 which are securely fastened to the hoopings and staves of the silo walls. Located beneath and extending parallel with these upright posts are the members 9 which are provided with the downwardly extending serrated edges 10. These edges 10 are adapted to be driven into the hoops 1 in order that the entire structure will not be in any way weakened by reason of the door opening.

In order that the upright posts 7 and 8 may be spaced and maintained the proper distance apart, suitable rods 11 are interposed therebetween, said rods being provided at their ends with engaging nuts thereon which are adapted to clamp and extend transversely through the upright posts 7 and 8, which will be hereinafter termed stiles. In order that the door frame may be further strengthened and also in order that a convenient step may be provided, there is installed at various intervals along the upright stiles the cross beams 12.

The closure for the opening in the silo wall is composed of a plurality of hingedly mounted doors 13, the lower edge of the lowest door and the upper edge of the upper most door being suitably beveied in order that they may wedgedly engage the beveled edges 4 and 3 of the door frame respectively. The upper edge of the doors with the exception of the uppermost door, are provided with the metal protecting strip 14 which metal strip is angular in cross section and is adapted to prevent the marring of the door edge which would be liable to render the joints between the various doors leaky, which feature is objectionable. lhe upper edge of the door is composed of the angular or inclined edge 15, the upwardly extending edge 16 adjacent thereto and the horizontal edge 17 upon which the inner angle leg is adapted to be fastened. The lower edges of the doors are made to conform with the upper edge of the door sub-adjacent and the various doors are held in position and wedged tightly in place by means of the edges of the lower and upper doors contacting with the beveled edges of the upper and lower door frames as heleinbefore S a d! The various doors are hingedly mounted upon the upright stile 7 by means of the hinge provided with the arms 18 and 19 which suitably engage the hinged eye bolts 20 and 21. The arms 18 and 19 are provided with downwardly extending projections which are positioned within the eye bolts 20 and 21 and held therein by means of a bolt fastened to the stile at a position a slight distance above the hinged eye bolt :21 after the hinge has been positioned therein. This double hinged member composed of the arms 18 and 19 extends 0utwardly toward the door center and merge into contact at a point 23, the two arms at this point being suitably welded or otherwise rigidly held together, beyond which the arms again separate to form a double hinged connection with the center of the door 13 by engaging the suitable hinged eye bolt 24 suitably mounted upon and located centrally of the door. A top view of the outline of this hinged member is substantially hook-shaped as illustrated in Fig. 3, in which the hooked end of the hinge is mounted to the stile 7 and the end remote therefrom hingedly connected to the door center. This construction will allow the door to swing inwardly and behind the door frame as illustrated in the dotted lines in Fig. 3.

In order that the various doorsmay be held in a closed position, the latch members 25 have been provided, which members are pivotally mounted upon the various doors by means of the pivots 26. One end of this latch member is adapted to engage a suitably formed notch within the door frame member or stile 7. These various latch members are adapted to force the doors into contact with the channeled edge 6 and beveled edge 5 of the silo door opening. Furthermore it will force the doors between the inclined upper and lower edges of this door frame to thereby insure that the various door joints will be liquid tight which is a very important consideration.

the straight portion, when viewed in eleva tion, being made up of upper and lower arms which diverge toward their inner and outer ends, and are concaved into bracing contact intermediate their ends; the inner ends of the arms being united by an integral portion which is pivoted to the door, at a point approximately midway between the vertical edges of the door, the outer ends of the arms terminating in pintles pivotally received by the frame.

In testimony that I claim the foregoing as my own, I have hereto allixed my signature in the presence of two witnesses.
